Application flied 1.1.10, 1905.. Serial No. 26 .096.

To all whomit may concern:

Be it known that I, ERNESTO. WHITE, a

citizen of the United States, residing at Liberty, in the county of Sullivan and State of New York, have invented certain new and 'useful Improvements in Fasteners for Beceptacles, of which the. following is a specifi- -,cation.

This invention embodies a novel form of locking-catch for covers of flasks, boxes, or receptacles of any kind.

The object of the invention is to provide a catch of this type afiording protection against accidental disengagement thereof from the keeper with which it cooperates and operable by an unlocking device in such manner as to afford theprotection above mentioned.

In carrying out the invention the unlocking device by which the catch is actuated to' effect its re ease necessitates movement in two directions in order to effect disengage- -ment of the catch, and for this reason hkelihood of accidental release or disengagement is remote, as the combined movement of the unlocking device cannot be effected by accident, though admitting of ready performance upon manipulation thereof by the operatorQ For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to .be had to the following description and accompanying drawings, in which Figure 1 is a view showing a receptacle in dotted lines, a portion of the receptacle being shown in section in full lines and the invention a plied to this portion. Fig. 2 is an enw large view showing more clearly thelockingcatch and operating parts in positions assumed thereby when the receptacle is closed. Fig. 3 is a view in section similar to Fi 2, the unlockin device having been pushe in wardly as w en initially operated prepara tory to di sengaging the catch. Figs. 4 and 5 are snmlar views showing thecatch disengaged by the unlocking device, the latter I be1ng at opposite limits of movement to accomplish such disengagement. Fig. 6 is a broken view in elevation showing the forma tion of the socket receiving the head of the unlocking device. Fig. 7 is .a detail view-of the unlocking-device alone.

Correspon g and like parts at opposite points.

are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters.

In the drawings the numeral 1 designates the body of the receptacle, and 2 the cover thereof, the latter having a suitable keeper 3, with which the catch 4 is adapted to engage. The catch 4 is provided at one end with a hook or finger 4 which is designed to enggge a shoulder 3 on the keeper to effect 'ng engagement between the two parts. The catch 4 is a spring-catch and is attached near one end to the receptacle 1 in any substantial way, the spring tendency of the catch being such as to normally hold the same in engagement with the keeper 3. The body of the catch 4 is curved between the ends thereof to form oppositely-extending inclined portions 4*, constituting cams virtu ally, the portions 4 coacting with an unlocking device 5 in the actual manipulation of the parts of the device.

The unlocking device 5 consists of a knob or button constituting a handle and from which projects a short stem 6, at the outer end of which is formed a semicircular head 7. The head 7 has its outer side in contact with theinner side of the catch 4 and longitudinal movement of. the unlocking device 5 will.

carry the {head 7 {longitudinally of the catch in contact therewith, such movement causing the catch to be disengaged from the keeper 3. The unlocking device 5 is designed to remain permanently upon the receptacle, and to affix the same thereto the head 7 is passed through an opening 8 in a side of the receptacle 1, said opening having slots 9 extending therefrom The side of the receptacle 1 adjacent the opening 8 is formed with slits 10, which admit of springing the head 7 of the unlocking device 5 through the opening 8, said head being slightly larger than the opening. The slots 9 are formed so as to contact with the locking part on the stem 6 of the unlocking device 5, said locking art being a shoulderll at the innerside o the head 7 The shoulder 11 is of a diameter about 6%1181 to the'dia'meter of the opening 8, w 'lo the stem 6 is of a width about equal to the width ofthe slots 9. The spring tendenc of the catch 4 is such as to normally tend to old the unlocking device 5 in the ino erative position shownin Fig. 2 or with t e shoulder 11 in the opening8, it not being adaptedfor slidable movement elth'er up or down when said shoulder 11 is in such position. When the shoulder 11 is in the opening 8, the head 7 rests at the point where the inclined portions 4 of the catch 4 meet, and when the catch 4 bears against the head 7 it normally tends to force the head into this position, as shown in Fig. 2. By pressing the handle of the unlocking device 5 inwardly or toward the catch 4, however, the shoulder 1 1 is displaced from, the opening 8 and the unlocking device 5 may e moved upwardly or downwardly b slidable movement so that the stem 6 wil be forced into either of the slots 9, according to the direction of movement. -On forcing the unlocking device into a position such that the stem 6 enters one of the slots 9, it will be seen that the head 7 will ride along one of the inclined portions 4 of the catch 4 and the cam action producedin this way forces the catch out of engagement with the keeper 3, as shown most clearly in Figs. 4 and 5 of the drawings. When forced out of engagement with the kee er 3, the catch 4 readily admits of opening the receptacle 1. As soon as the unlocking device 5 is released, however, the s ringressure of the catch 4 against the hea 7 ten s to force said head to the oint at which the inclines 4* meet, or, in ct er words, the catch 4 automatunlocking device t at such movement will noteffect the complete release of the catch, but will merely eifect a partial release thereof and will cause the catch to move only to a position where its hook or finger 4 is still in en gagementwith the shoulder 3 of the keeper 3. This will be best understood by reference to Figs. 2 and 3 of the accompanying drawings. In Fig. 2 it will be noticed that the catch 4 is in full engagement with the keeper and that the unlockin device is pressed by the catch so that its shou der 11 is received in the opening 8 and is thereby held in inoperative position. Now to effect a full release of the catch it is necessary, first, to press inwardl upon the handle of the unlocking device until said knob or handle engages the adjacent wall of the receptacle which forms a lock or stop for the inward movement of the unlocking device. The position then taken by the unlocking device is shown in Fig. 3. Here it will be seen thatthis inward pressing of the unlocking device to eiiecta release of the shoulder 11 from the opening 8-has moved eaaaee the catch 4 only far enough to effect a partial disengagement between its hook or finger 4 and the shoulder 3 of the keeper 3. The cover cannot yet be raised. To effect a comlete release of the locking-catch 4, the unocking device must be slid in one direction or another while it is still in the inwardlypfessed position, as has been before described. ence it will be noticed, first, that the latch holds the unlocking device in an inoperative position, where it is impossible to move it up or down or in any direction to effect the complete release of the catch; second, that it is st necessary to press the unlocking device inwardly to effect a partial release of the catch, and, third, that it is then necessary to move the unlocking device in still another direction to effect the complete disengagement of the catch from its keeper. It is thus" to be understood that my invention provides sure means for reventing the accidental release of the loc ing-catch, because the combined movement necessary to effect the complete release of the catch is manifestly unikely to be effected b accident, although its erformance in 'actua use by proper mani uation may readily be accomplished. 'l he locking-catch aforesaid is extremely sim is in its construction and revents all likelihood of accidental opening 0 the receptacle with provision for quick intentional opening under proper manlpulation, the advantages of the oregoing being obvious and of no small importance.

The locking-catch in its principle may of course be applied in various ways in securing parts together.
